With her cheeky smile and love of practical jokes, Lincoln Tesco cashier Mary Boyer says she is sad to be retiring from her job after 40 years.

Mary, 76, from Nettleham, has seen all manner of changes in her time, including the advent of customers scanning their own items, 24-hour shopping, Sunday trading, and the uniform going from red to blue.

But a constant for her throughout has been looking after her customers.

Mary's last day on the tills at Tesco Extra in Wragby Road is on Saturday, March 16 and she takes so many memories with her.
